The uses for silica fume in concrete:
&©|61623;decrease the temperature effect that occurs during the cement hydration.
&©|61623;improve the workability of concrete.
&©|61623;increase the initial and also final setting time.
&©|61623;decrease the total porosity of concrete and significantly reduce the permeability.
&©|61623;improve the compressive strength as well as the tensile and flexural strength of concrete.
&©|61623;enhance the early age mechanical properties as well as long-term strength properties of concrete.
&©|61623;reduce the water penetration into concrete by capillary action.
&©|61623;improve the resistance of concrete to sulphate attack effectively.
Compressive strength: Normally use of Micro Silica in the below mentioned percentages enhances the compressive strength of concrete.
&©|61623;10% to 15% - High strength structural columns
&©|61623;10% - Flatwork
&©|61623;8% to 10% - High durability / Low permeability such as bridge decks or parking structures
&©|61623;8% to 15% - by weight of cement but as an addition not replacement.
Advantages of adding silica fume in concrete:
&©|61623;Increased compressive and flexural strengths
&©|61623;Reduced permeability
&©|61623;Increased resistance to chemical attack
&©|61623;Increased durability
&©|61623;Reduced effects of alkali-silica reactivity
&©|61623;Reduced shrinkage due to particle packing, making concrete denser
&©|61623;Enhanced workability of concrete
&©|61623;Reduced heat gain through the walls of buildings
&©|61623;Reduced amount of super plasticizer
&©|61623;Reduced potential for efflorescence due to reduced calcium hydracids |
